What is the OUI 10:44:5A?

10:44:5A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shaanxi Hitech Electronic Co., LTD. It covers every address from 10:44:5A:00:00:00 to 10:44:5A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-44-5A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:44:5A:00:00:00 that is 10:44:5A — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Shaanxi Hitech Electronic Co., LTD located?

Shaanxi Hitech Electronic Co., LTD is listed at 35 Tuanjienan Rode, Xian Shaanxi CN 710075 in the IEEE OUI registry entry for 10:44:5A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
